This article investigates resonant transmission phenomena through a single metallic subwavelength slit when the permittivity of a real metal varies. The single metallic slit is utilized as a metal–insulator–metal waveguide, and a mode-matching technique is employed to obtain the transmitted power. The periodic resonant transmission phenomena (in terms of the metallic plate thickness) are solved, and the resonances can be understood by their guide wavelengths. Even when the permittivity of the real metal includes imaginary parts (i.e., metal with loss), the resonant transmittances are obtained. However, the peaks of the transmittances decrease, as the plate thickness increases. The orthogonal relationship of an incomplete orthogonal set is maintained despite metallic loss (given a relatively small amount of loss), due to the complex permittivity of the real metal.

This book promises a ‘radical reappraisal’ (Kates 2005, xv) of Derrida, concentrating particularly on the relationship of Derrida to philosophy, one of the most vexed questions in the reception of his work. The aim of the book is to provide the grounds for this reappraisal through a reinterpretation in particular of two of the major works Derrida published in 1967: Speech and Phenomena and Of Grammatology. However the study of the development of Derrida's work is the real achievement of the book as Kates discusses major works dating from the 1954 study of genesis in Husserl's phenomenology through to the essays on Levinas and Foucault in the early 1960's as part of his story of how Derrida arrived at the writing of the two major works from 1967.

A tunable demultiplexer with three output channels infiltrated by liquid crystal (LC) is presented, which is based on a metal-insulator-metal (MIM) waveguide. The operating frequencies of the three output channels can be tuned simultaneously at will by changing the external bias electric field applied to the LC. By analyzing the Fabry-Pérot (FP) resonance modes of the finite-length MIM waveguide both theoretically and numerically, the locations of the three channels are delicately determined to achieve the best demultiplexing effects. Terahertz (THz) signals input from the main channel can be demultiplexed by channels 1, 2 and 3 at 0.7135 THz, 1.068 THz and 1.429 THz, respectively. By applying an external electric field to alter the tilt angle of the infiltrating LC material, the operating frequencies of channels 1, 2 and 3 can be relatively shifted up to 12.3%, 9.6% and 9.7%, respectively. The designed demultiplexer can not only provide a flexible means to demultiplex signals but also tune operating bands of output channels at the same time.

Introduction: at present the reader’s audience is particularly interested in creative experiments in which the historical fate of the Russian peasantry in the «turning» eras is artistically comprehended. The article is devoted to the study of the problem-thematic range of modern Mordovian historical prose. The subject of analysis is the peculiarity of the reception of the period of collectivization and dekulakization in the story by Erzyan prose writer A. Doronin «A Wolf Ravine». Objective: to reveal the features of the artistic reconstruction of the events of the 1930s, the modeling of the relationship between a man and society in the story by A. Doronin «A Wolf Ravine».Research materials: the story by A. Doronin «A Wolf Ravine». Results and novelty of the research: the historical story « A Wolf Ravine » for the first time becomes the object of scientific understanding and is introduced into the context of Finno-Ugric literary criticism. A. Doronin artistically interprets the real events and circumstances of the resettlement of dispossessed peasants of the Volga region to the uninhabited steppes of Kazakhstan. As a result of the study, we conclude that the actualization of this problem-thematic cluster is due to the creative concept of the historical writer; the individual author’s approach to the reconstruction of historical narrative can be traced in the writer’s desire to realistically reveal the relationship of personality and society in the tragic 1930s; to analyze intentions of people and of the psychological states of the characters. Problems of a sociopolitical nature, actualized in the story, are filled with philosophical, axiological content, and lead to a multi-faceted understanding of the «man and history» problem.

Marriage is a sacred bond in Islam that ties a man and a woman into a lifelong relationship of love, compassion, mutual understanding, respect and security. It is a firm pledge that one makes in the name of Allah for one-another. ‘Misyar marriage’, ‘Convenience marriage’ or ‘Travelers’ marriage’ is a new form of marriage practiced widely in Saudi Arabia, Egypt and other gulf states. The ‘Misyar bride’ sacrifices some of her marital rights, such as expenses, fixed duration, and an abode. The scholars in Islam have different opinions about this form of marriage. Some of them supported it vehemently, as it could reduce the number of ladies without husbands; while yet others strongly oppose it, as it sounds like part-time wives, which has no roots in Islamic heritage. The present study therefore aims to explore the real status of ‘Misyar or convenience marriage’ in the texts from the Qur’an, Prophet’s Sunnah, the practices of his rightly guided Companions and the Fatawa of the traditional and modern scholars. It would analyze them in the light of the current realities and situations prevailing in many countries of the Muslim world. The study would adopt a critical yet objective approach in dealing with the issue. It is believed that the study would help the Muslim men and women to have clear insights on the issue based on the Shari`ah texts, scholars’ Fatawa and present day realities.
